My invention consists in a new and useful improvement in drip panstandis designed more particularly to provide a pan for. use with thecarburetor float chamber of an outboard motor. During years of almostdaily use of outboard motors for seven months of each year, and havingowned five different types and sizes of motors, I have found that themost annoying feature of this kind of motor is the spilling of mixedgasoline and lubricating oil from the carburetor float chamber, everytime the motor istilted. In motors of this character, as is well known,the lubricating oil must be supplied with the fuel, through thecarburetor, with the inevitable result that any discharge from the floatchamber has in it this lubricating oil, and while the gasoline which isspilt evaporates, the oil remains, so that the oily mess has to bewipedofl of the stern seat and out of the bilge continually. Otherwise theafterpart of the boat is no fit place to be, unless one wears workingclothes. With most outboard motors, tilt- U ing is necessary inre-fueling, and is always necessary in clearing the propeller from weedsor sea grass. It is always done when the boat is beached, and frequentlyin driving the boat over shoals and bars. At night,

most motors being too unwieldy and heavy to be easily removed from theboat, they are tilted so that the propeller and underwater gear-housingclear the water. 'On each and all of these occasions, the mixed gasolineand oil remaining in the carburetor float chamher when the motor isstopped drain out-into the boat and eventually into the bilges. Myimproved drip pan entirely obviates this very disagreeable feature ofthe outboard motor.

By the use of my improved device, all mixed gasoline and oil which is inthe carburetor float chamber, when the motor is stopped, drains out intoa small receptacle attached to the float chamber, and flows over theside through a flexible tube when the motor is tilted back into runningposition. Also, any overflow, from flooding of the float chamber whilethe engine is running, is caught in the receptacle and drains over theside. When my device has been installed,

the rear seat and bilges will be kept entirely free from gasoline andoil, and the whole after part of the boat will be clean enough to beoccupied by a driver in white duck clothing. The device weighs but a fewounces, can

be made tofit any carburetor float chamber, and can be installed quicklyand easily by any one. I Since it has no moving parts to wear, it willlast indefinitely.

While-I have illustrated in the drawings filed herewith and havehereinafter fully described one specific'embodiment of my invention,.it'is to be distinctly understood that I do not consider my inventionlimitedto said specific embodiment, but refer for its, scope to theclaims apended hereto.-

Fig. 8 is a bottom-plan view of the device illustrated in Fig. 7. V

Fig. 9 is a bottom plan view of the modified form of my device designedfor application to a float chamber upon the right side ofthe carburetor.7 V j r In the drawings:

The outboard motor M is pivoted to the clamp C applied to-the transom ofthe boat, by the pintle pin P, and has the carburetor float chamber F onthe carburetor-It, and the fuel tank T with fuel line L to thecarburetor R, having the petcock S. 'My improved drip pan D may be madeof any suitable material and fabricated byany suitable method so as tohave the two walls 1 and 2 Y Y with the extension walls 5 and the lip 6,

forming a cup at right angles to thetrough As can be observed from Figs.1 and 2,

the parts of my improved pan D are so designed that the pan D will fitabout the float chamber F, the walls 1 and 2 embracing the cylindricalchamber F and the extension walls 5 and lip 6 fitting below the chamberF.

In order to adjust the pan D to the chamber F, I provide an arcuatespring collar 7;

w and to this spout 11, I attacha suitable drain pipe 13 which may besuitably supported by a guide 1 1 attached to the motor M. i

In Figs. 7, 8 and 9, I have illustrated a modified form ofmy improvedpan D, the article being made to fit a particular'float chamber F."Inthis form, since the pan D is intended to be used upon only onetypeof float chamber F, the spout 11a is deflected toward either theright or left side, according to Whether the float chamber F is upon theright or left side of the motor M, and the attaching collar 7a ispermanently attached to the walls 1 and 2 by rivets 15. In this form,also, the collar 7a may be dispensed with, and the pan D attached totheyfloat chamber 'F by means of tapped bolts.

From the foregoing description of the details of construction of myimproved pan D, its-use will be obvious. IVhen the motor M is moved intoinoperative position, as illustrated in Fig 1, for any reason, thetipping of the float chamber F will cause escape of gasoline.

and oil. This is necessary, since it is'impossible to seal the chamberF. It is obvious from Fig. 1 that my improved pan D is so disposed, whenthe motor M is tipped, as to catch any gasoline and oil escaping fromthe chamber F in the trough formed by the walls 1 and 2. When the motorM is again moved into operative position, as illustrated in Fig. 2, itis obvious that the escaped liquid, trapped in the cup of pan D, flowsout through the spout 1'1 and pipe 13 over the side. 7 Having describedmy invention, what I claim is:

1. In a drip pan for the float chamber of the carburetor of an outboardmotor, the combination of a trough having one of its ends fitted overthe top of said chamber; and

a cup formed at the other end of said trough forsaid cup.
